Coal Mining Coal can be extracted from the earth either by surface mining or underground mining. Once coal has been extracted, it can be used directly (for heating and industrial processes) or to fuel power plants for electricity. Surface Mining If coal is less than 61 meters (200 feet) underground, it can be extracted through surface mining.
In most of the large surface mines in India, the coal is loosened with the help of drilling and blasting techniques and transported using the shoveldumper combination. Draglines remove the top layer of overburden. Quite often, several draglines work in tandem for overburden handling. At certain coal mines, surface miners are used to extract ...
